FIG. 2.

Partial complementation of yeast Δyap1 hydrogen peroxide sensitivity by C. heterostrophus CHAP1 cDNA. Yeast strains were tested for growth in the presence of 0.2 and 0.5 mM hydrogen peroxide. The Δyap1/pYES2 and Δyap1/CHAP1 Δyap1 mutant yeast strains were transformed with empty expression vector pYES2 and a vector containing CHAP1 cDNA, respectively. BY4742/pYES2 and BY4742/CHAP1 are the parental wild-type yeast strain with the same genetic background as the mutant transformed with empty pYES2 and pYES2 containing CHAP1, respectively.
